Comparing Lutron’s Control Systems to Find the Best Solution for Your Home

If you’re reading this, there’s a strong chance that you’re interested in smart lighting control. Congrats! You’ve come to the right place. We’re a Bay Area Lutron dealer that designs and installs custom lighting systems that adapt to your daily routines and activities.

Lutron is a world leader in smart lighting, but not all of its solutions are the same. Lutron offers three control system options: Caséta, RadioRA 3, and HomeWorks.

As a Lutron dealer, we can typically tell which control system to install based on a homeowner’s needs and preferences. But if you’re curious, here’s what each system does differently and how they may (or may not) be suited to your San Francisco home.

Caséta is Lutron’s most basic lighting control system, referred to as a “mini system” for single rooms or small homes. Caséta is a wireless solution that uses radio frequencies to communicate with lights and motorized shades. It’s best for homes up to 2,500 square feet and can control up to 75 devices. That may sound like a lot, but consider how many window shades, thermostats, indoor and outdoor lights you’d like to control.

Caséta is a great option for small-scale installations, but its control and automation capabilities are limited. It can be controlled by the Pico remote and Lutron app, but not dimming panels. More complex automations require programming that Caséta is not built for.

RadioRA 3

RadioRA 3 is a wireless whole-home lighting system. Since it’s wireless, RadioRA 3 is an ideal choice when it’s not feasible to run wires through the walls. RadioRA 3 can cover up to 7,500 square feet, 200 devices, and five wireless temperature sensors, making it a step above Caséta for larger houses.


Finally, there’s HomeWorks, Lutron’s most sophisticated whole-home system. HomeWorks is capable of both wireless and wired communication, and with wiring, comes much more reliable performance and more customized programming. HomeWorks is the best option for new construction, as your home’s walls will be open for low-voltage wiring.

HomeWorks can cover up to 50,000 square feet and 10,000 lighting zones, making it the best choice for large estates and luxury homes. When compared to RadioRA 3, HomeWorks unlocks many more possibilities. Its conditional if/then logic means when you perform certain actions at home, your lights will intelligently respond. For instance, if you return home at night, it knows what lights to turn on and sets them to a preferred brightness level. But when you walk through the door during the day, different lighting settings will activate.

If you’re ready to bring awe-inspiring lighting to your Bay Area home, Hermary’s is a certified Lutron dealer and home technology installer. Contact our team here to learn more and for a complimentary consultation. We look forward to working with you!
